ILLIQUIDITY COMPONENT OF CREDIT RISK

We provide a theoretical decomposition of bank credit risk into insolvency risk and illiquidity risk, defining illiquidity risk to be the counterfactual probability of failure due to a run when the bank would have survived in the absence of a run. We show that illiquidity risk is (i) decreasing in the liquidity ratiothe ratio of realizable cash on the balance sheet to short-term liabilities; (ii) decreasing in the excess return of debt; and (iii) increasing in the solvency uncertaintya measure of the variance of the asset portfolio.
